Be it known that I, J ULES H.

This invention relates to improvements in A steam pipe 11 is providedwith valve apparatus for makin producer gas. controlled branch pipes 12,13, 1 1, and two The object of the invention is to provide of thesebranch pipes 12, 13, communicate a producer for making gas from thecomwith the gas generating chamber 3 at adjabustion of a continuousstream of gas-formcent points slightly in advance of the point ingcombustible material mixed with air of communication of inlet pipe 15with said and the subsequent combination of gases gas generating chamber3. These branch formed by the decomposition of steam or pipes 12, 13,are also slightly upwardly other moisture and recomposition of theredirected to said gas generating chamber 3. sulting gases with thegases evolved by the Branch pipe 14 passes upwardly through saidcombustion, wall 2 and at the highest point of the wall '70 Theadmission of steam or other moisture 2, communicates with the gasgenerating is for the purpose of adding hydrogen to chamber 3. Asupplementary valved gas the resulting gases and to secure amaxistarting inlet pipe 72 communicates with inmum pr'ecentage of carbonmonoxid in the let pipe 7, said inlet pipe being forwardly resultinggases. The process involved in the directed at the point ofcommunication. A 75 of any gas off-take pipe 5 communicates with thepassage 4 at a point intermediate the gas generating chamber 3 and thewater seal 6. This off-take pipe 5 passes to any point where it isdesired to use the gas generated in the gas producer.

' Operation: A carbonaceous material having been introduced into thehoppers 8, 16, the blowing means 10 is caused to operate, directing ablast of air axially into the outer end of inlet pipe 7 and past thedischarge end of the hopper 8, the gate 9 having been adj usted to asuitable opening. Under these conditions, the ignition of the chargeentering the other inlet pipe 7 having been effected in any suitablemanner as by starting gas inlet '72, the gas-forming combustiblematerial consisting of an admixture of finely divided carbonaceousmaterial and air, will be carried upwardly through the gas generatingchamber 3 and around the top of wall 2 down through passage 4 toward theoffoperation of the producer herein disclosed, is claimed in Patent1,039,398, granted Sept.

The accompanying drawing illustrates one of the embodiments of theinvention and from a study of the same as described in thespecification, a clear conception of the invention may be had.

The single figure of the drawing is a vertical section through the gasproducer.

Referring to the drawing, the furnace 1 is suitable configuration and isshown as vertically disposed with its interior preferably dome shaped atthe top. This interior of the furnace is divided by a vertical wall 2into the gas generating chamber 3 and the narrow passage 4 leading atthe bottom to the water seal 6. An inlet pipe 7 leads to the bottom ofthe gas generating chamber 3 and is upwardly directed. At its outer enda hopper 8 controlled by a gate 9 near its bottom is in communicationtherewith, and

a blowing means 10, such as a blower or fan. take pipe 5. During itspassage combustion is directed into the open end of the inlet pipe willtake place and the condition of com- 7 adjacent the communication fromthe pleteness of such combustion will be deterhopper 8. A supplementaryinlet pipe 15 mined by various conditions as to the extent hopper gate 9and the also upon other exsuch as the temperature of opening of theblowing means 10; traneous conditions,

communicates with the gas generating chamber 3 at a point slightly inadvance of the point at which the inlet pipe 7 communicates variousbranch of the gas producer.- proceeded for a time, the as producer wilbecome highly heated especially in the upper part of the gas generatingchamber 3. In

order to control the extent of the temperai ture rise, steam isintroduced through the pipes 12,13, 14, and'these varlous points ofintroduction of the steam are designed to be at points of highesttemperature. A chemical reaction takes place causing the disassociatio-nof the elements of the steam or moisture into hydrogen and oxygen with asubsequent recompositio'n' of these gases wholly or in part with agasf'orming combustible material burning in the gas generating chamber3. Free hydrogen, methane or marsh gas, carbon monoxid, and possiblycarbon dioxid, will be some or all of the resulting gases.-

In orderto reduce any carbon dioxid that may be formed within thegasgenerating chamber 3, a supplemental intro uction of gas-formingcombustible material is made through the inlet pipe 15 by using theblowing means 17 in combination with the gas controlled hopper 16 havingtherein carbonaceous material. This carbonaceous material beingintroduced at a point of high temperature within the gas generatingCombustion having I communicating with the sage is directed, and

chamber 3, unites with the carbon dio'xid gas, if any there be, reducingsame to carbon monoxid. The air introduced through the blowing means 17combines with other carbonaceous material introduced thereby, theadjustment being such that the carbonaceous material is in excess.

The gasfDI'HliDg combustible material in'- t'roduced either through themain inlet pipe 7 or the supplemental inlet pipe 15, may consist ofliquid hydrocarbon and air instead'of carbonaceous material and air."The ash formed by thecombustion, and any excess of solid materialintroduced into the producer, pass down through the passage 4 into thewater seal 6 from whence they may be externally removed without stoppingthe main operation of the producer and without opening up communicationfrom within the same to the atmosphere.

It should be understood that it is not desired to be limited to theexact details of d construction shown and described, for obviousmodifications will occur to a person skilled in the art.

It is claimed and desired to secure by Let ters Patent,-
